Piezoresistive Pressure Transmitters Type 21Y


The 21 Y product line is exceptional for its extreme robustness against electromagnetic fields. Range up to 1000 bar, 4 ... 20 mA outputs, 0 ... 10, 0.5 ... 4.5 V. The limits of the CE standard are up to a factor of 10 with driven and irradiated fields. These transmitters are also extremely immune to external voltages between the housing and the electrical connection, which is particularly important when using frequency converters. The high insulation voltage of 300 V makes this product ideal for use in the most difficult environments. The extension of the vertical production range, the modular design and the programmable electronics allow to realize large batches, specific for the customer.
